C9 MPD updates.

Tech was out and checked for software updates.Engine software was current.MPD software has had seven updates.He did not know what the updates modified but did caution me that other operators wish they would have kept the old.His advice was that if I am happy with the information MPD supplies now I might want to keep it as it is not easy to “go back” with the updates.What would change if I updated to the current software?
